Carrie Underwood's pregnancy announcement causes confusion

Underwood and husband Mike Fisher are expecting a baby, according to the Los Angeles Times.

The country music star and the professional hockey player announced the big news Monday with a Labor Day pun and a dog photo.

"In honor of 'Labor' Day ... Ace & Penny would like to make an announcement. Their parents couldn't be happier!" Underwood posted on Twitter and Instagram, with a photo of her with the couple's two dogs. One dog wore a shirt saying, "I'm going to be a big brother," while the other's said, "I'm going to be a big sister."

Yeah ... how do you think Carrie Underwood would react of she went into labor and another dog came out?
